A computer architecture and programming model for high speed processing over broadband networks are provided. The architecture employs a consistent modular structure, a common computing module and uniform software cells. The common computing module includes a control processor, a plurality of processing units, a plurality of local memories from which the processing units process programs, a direct memory access controller and a shared main memory. A synchronized system and method for the coordinated reading and writing of data to and from the shared main memory by the processing units also are provided. A hardware sandbox structure is provided for security against the corruption of data among the programs being processed by the processing units. The uniform software cells contain both data and applications and are structured for processing by any of the processors of the network. Each software cell is uniquely identified on the network. A system and method for creating a dedicated pipeline for processing streaming data also are provided.

This is a continuation of commonly assigned, U.S. patent application entitled "Memory Protection System and Method for Computer Architecture for Broadband Networks," application Ser. No. 09/816020, filed Mar. 22, 2001 now U.S. Pat. No. 6,526,491; the disclosure of which is incorporated by reference herein.
A memory controller to provide memory access services in an adaptive computing engine is provided. The controller comprises: a network interface configured to receive a memory request from a programmable network; and a memory interface configured to access a memory to fulfill the memory request from the programmable network, wherein the memory interface receives and provides data for the memory request to the network interface, the network interface configured to send data to and receive data from the programmable network.
With commands from a terminal divided into a command to designate an access area and a command to gain access, the terminal adds verification data of the terminal to an argument of the command to gain access, and it is thereby possible to verify the identity of a terminal application that issues the command to designate an access area, a terminal application that issues the command to gain access, and a terminal application that holds a verification key.
